Beyond tease and denial, our women have even more devious means to control your sexual responses. One of the very most frustrating, more so even than orgasm denial, is a ruined orgasm. Rather than simply arousing her sub, some of our cruel mistresses will actually bring them to the border of orgasm, and then deny them stimulation in those last few crucial seconds.
Of course, 99% of the time the sub comes anyway, but it is extremely anticlimactic and not at all satisfying. Now instead of simply running off to masturbate on their own, they have to wait for the batteries to recharge, and must also endure the mortification of having their erection melt away in front of their mistress, which can only result in further name calling and humiliation.
